sign_and_encrypt Method

Signs and encrypts the current message.

Syntax

def sign_and_encrypt() -> None: ...

Remarks

This method both signs and encrypts the input message into a single PKCS encoded envelope. The value in detached_signature is ignored: the class will always generate an attached signature when calling this method. All other properties used by calling the sign and encrypt methods are used in the same manner.

Please note that the message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity, and providing other headers for the S/MIME wrapper.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

• input_file
• input_message

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

• output_file
• output_message: The output data is written to this property if no other destination is specified.

The headers of the input message (if any) will be read from input_message_headers or input_message_headers_string.

The headers of the resulting message will be available in the output_message_headers and output_message_headers_string properties.
